INIPROYBD WOODEN RAILWAY.

The Schedule referred to in these Letters .Patent and making part of the carneA M T0 au whom "t 'may WWW" ,engine and cars run upon the upper surface, the weight Beit known that I, J OHN Y. SMITH, of Pittsburg, in` of the same will be directly over the central portion the county of Allegheny, and State of Pennsylvania, ofthe base of the rail, thus distributing such weight have invented anew and useful lmprcvement'in Railequally over such surface.

roads; and I do hereby declare that the following is a Another important advantage resulting from this full, clear, and exact description of the same, reference form of rail is,vthat,` as the wedge-form of the flange w., being had to the annexed drawings, making part of this Vof the wheel nearly corresponds with the rail, or that specification, in whichportion of it with which the flange comes in contact, Figure 1 is a plan or top view of my improved railit will constantly operate to-throw such wheel away from way-track, 'showing lso a plan view of a modified form the rail, and thus the-danger of the wheels mounting of rail, and of the plank or timber from which the rails the rails is avoided', and especiL lly is this the case in may be cut; running around the curves which occur in all lines o Figure 2 is an end view, showing the rails in position road.l E in the notches, or recesses, formed in the cross-ties; A' represents; a modid form of the rail, an end Figure 3 is an end view of a modified form of the view of which is shownin `iig. 3 of the drawings. 1t is apparent that this form of rail possesses nearly rail Figure 4 is 'an end view of the plank from which the rails may be cut;

Figure 5 is a sectional elevation of the machine for sawing the sides of the notches in the ties, for the reception of th'e rails;

Figure 6 is a lan or top view of the sawing-machine, showing the arrangement of the saws for cuttin .the bevel in the ties, for receiving the bevelled edge of the rail, and also the bevelled or wedge-shaped keri, for the bevelled edgeof the wedge to bear against;

l i Figure 7 is a bottom view of the same machine,

showing the arrangement of the saws, and the jour nal-boxes through which they slide,

The same letters in all the figures indicate identiall the advantages ascribed to the one above described, and that both forms obviate the necessi y of chamfering the inner edge ofthe rail--a saving of time and'material not effected 4by any other form of wooden rail within my knowledge.

B represents the cross-ties, which have notches, or recesses, formed in their upper surfaces, for the recepta tion of the rail, as above stated.

' The inner ends or surfaces of each-of these recesses are to be sawed, so as to correspond with the bevelled edges of the rails, so that,as the rail is placed therein, the eiect of 4retaining it, above described, is produced.

The opposite surface, or end, of thisrecess has a bevelled surface, for receiving the wedge which holdsthe ail.

p G represents a wedge, which is to be driven between the edge of the rail and the outer bevclled end of the recess inthe tie, as shown in iig; 1 of the drawings.

D represents a plank, or stick of timber, which may have been previously reduced, by sawing, to the proper dimension for being cut or sawed into two rails, an en view of which is shown at fig. 4:.

1t will be sc en, thatby first cutting a log into planks as above indicated, and then sawing such planks througl the centre, much time and material will be saved, fo the reason that'the required bevel will be given to bot rails at one operation.

erstructure of railroads; and

1t consists-fo First, inthe construction of the rail of which the track is composed;

Secondly,in the construction of the tie, which receives and confines such rail; and, l

Thirdly, in the combination of such rail and tie, as will be more fully described hereafter.

A, in the drawings, represents the rails of my im-v proved track, which are made .entirely of wood, and o the configuration shown in iig. 2, where it will be seen that they are broader. at their base than they are upon their upperl surface, the objects of which are, first, to preventthe warping of the rails, and the consequent raising' of `themy out of the recess in the ties, and, secondly, forV the purpose of bringing the weight of the engine and car's uponorover the central portion of the surface which rests upon the ties.

It wili'be observed, that as a consequence of the peculiar form of the rail, it having one bevelled edge, when placed in the recess which is formed in the tie N for its reception, one end of which is of correspondin form, it will be impossible for any warping or springing of the rail to withdraw it from its vrestingplace in the tie. l

t 1t will also be observed, that as the wheels of the cal parts. n This invention relates to an improvement 1n the su- 'E represents a saw-frame, of ordinary constructie] upon which are to be mounted four circular saws, Fl and G G,which are for the purpose of cutting the be elled surfaces of the ends ofthe recesses inthe ties.

' 1t will be seen that the saws F and F are so arrange with reference to the saw-frame, that, as the tie is plac thereon, at a right,v angle to its greatest length, th may be moved in their bearings, and thus cut the be for the wedge which holds the rail in position; while i saws G and G are set at such an inclination, with i erence to the upper surface of the table, or saw-ben that, as-the tie is laid upon said table', and pushedl ward past such saws, the bevel or under cut, which responds with the bevel of the edge of the rail, wil formed. l

Both pairs of these saws are to be so arrange I have shown aud described an arrangement of saws for sawing the ties, in preparing them for the reception of the rails, only as a matter of information). as I do not now make any claim to such device.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is-l 1. The construction of 4the cross-tie with the vbevelled sm'face to receive the corresponding surface of thc Wedge, and with the opposite surface of its recess bevelled to correspond with the bevelled surface of the rail, substantially as shown and described.

2. The combination of the above-describedv rail A, tie B, and wedge C, substantially as .shown and described.

In testimony whereof, I have signed my name to this specification, in the presence of twol subscribing witnesses.
